UNIVERSAL DEVICE FOR ANALYSIS OF GRANULOMETRIC COMPOSITION OF SUSPENSIONS Russian patent published in 2011 - IPC G01N1/18 B04B11/00 

FIELD: machine building.

SUBSTANCE: device consists of rotating precipitating portion. A precipitator consists of a stabilising chamber, precipitating chamber and of a channel for centrate drainage. The precipitating chambers are divided with partitions with orifices for liquid flow. Precipitation is performed from a moving layer of liquid, while drying of sediment is done through additional orifices in the partitions between the chambers. The precipitating chamber rotates on a faceplate. A flat removable precipitating plate is set on the bottom of this chamber. Bigger particles settle near the partition between the stabilising and precipitating chambers, while finer particles settle further from the sad partition downstream on the flat removable precipitating plate. A rotating pipe line supplies suspension into the precipitator. The device is also equipped with a stationary portion of centrate reception made in form of a jacket for reception of centrate. A convex bottom of the jacket is inclined.

EFFECT: sedimentation of both large and fine particles of suspension during analysis, easy unloading of sediment with minimal losses and with maintaining order of settled particles.
